English translation:LD/LC50 values, EC/LC50
Explanation:
LD stands for lethal dose, LD50 is the dose that kills 50% of the experimental animals. LC stands for lethal concentration, EC as far as I can ascertain stands for effective concentration, the 50 is as above.

Thanks to all of you for your help. As to EC, since both environmental and effective concentration can be abbreviated
with EC, I will leave as is, but plan to consult with a microbiologist I know.

LD/LC50 , EC/LC50


Explanation:
LD/LC50 is the same in English. Refers to a test of toxins via oral, dermal, inhalation routes. URL below.

EC/LC50 is also the same. 2nd URL uses it, EC looks like exposure control, also discussed.

LD/LC50; EC/LC50 (see below)


Explanation:
From the URL below and a few others, and from dictionaries I believe that
LD stands for lethal dose (LD50 meaning that half of the organisms die when exposed);---that
LC stands for lethal concentration; --- and that EC stands for environmental concentration. (Souces: Reuter & Reture, Medizisches W., Eichhorn, Langenscheidts FWB Biologie.)
